11 SAU510-USB ISO PLUS v Bus Protocol Revision 1.00 JUL2013 The IEEE specification covers the requirements for JTAG bus of the target devices (such as the TMS320C6000 family) and provides certain rules summarized as follows: The TMS/TDI inputs are sampled on the rising edge of the device TCK signal. The TDO output is clocked from the falling edge of the device TCK signal. When JTAG devices are daisy-chained together, the TDO from each of the devices in the chain has a definite period in the TCK cycle. Such synchronization scheme allows to distinguish the data from different target devices included into the same chain. The penalty for this timing scheme is a reduced TCK frequency. The IEEE specification does not provide rules for JTAG bus master devices (e.g. emulator) Emulator Cable Pod Logic Figure 3-4 shows the JTAG connector of the emulator cable. Here are the key features of JTAG interface: TMS and TDI signals are generated from the rising edge of TCK_RET, on default (but the standard can be adjusted in the configuration file). The edges of TMS, TDI, TCK and TRST signals do not coincide in order to reduce signal echo. TCK equals 25-MHz on default. You may also set another level of TCK. Figure 3-4. Emulator Pod Connector 3.4. Emulator Cable Pod Signal Timing Figure 3-5 shows the clock signal timings for the emulator. Table 4 defines the timing parameters for the emulator. The timing parameters are for reference only, Sauris GmbH does not test them or guarantee their coincidence with the given in the table. The emulator pod uses TCK_RET as its clock source for internal synchronization. TCK can also be used as an optional test clock source for the target system. Figure 3-5.

TMS/TDI delay sets by POD_TMS_OFS and POD_TDO_OFS parameters Buffering Signals Between the Emulator and the Target System It is extremely important to provide high-quality signals between the emulator and the target system, especially the processor TCK and the emulator TCK_RET signals. In some cases this may require special PCB trace routing and using termination resistors to match the trace impedance. If the distance between the emulation header and the target device is longer than 15 cm, the emulation signals must be buffered. The need for signal buffering can be divided in two cases: No signal buffering. As shown in figure 3-6, the distance between the header and the target device does not exceed 15 cm. Figure 3-6. No Signal Buffering Buffered emulation signals. Figure 3-7 shows that the distance between the emulation header and the target device is longer than 15 cm. The target device signals TMS, TDI, TDO, and TCK_RET are buffered through several additional units. The EMU0 and EMU1 signals must have pull-ups to Vcc. The signal rise time of the pull-up resistors should be less than 10 μs. A 4.7k Ω resistor is suggested for most applications. EMU0-1 are I/O pins of the target device, however, they are inputs for the emulator only. These pins are used in multiprocessor systems to provide run/stop operations. Figure 3-7. Buffered Emulation Signals The emulator pod enables sequential termination of the TMS, TCK, and TDI signals. Figure 3-8 shows an application with the system test clock generated in the target system. The TCK signal is left unconnected in this application. There are two reasons for having the target system generating the test clock: o The emulator provides a 25-MHz test clock on default (the actual value can be adjusted in the configuration file). When using the target system test clock 12 Copyright 2013, Sauris GmbH

13 SAU510-USB ISO PLUS v.2 o Revision 1.00 JUL2013 you can set the frequency to match your system requirements. Sometimes the test clock is required when the Emulator is switched off.. Figure 3-8. Target System Generates Test Clock Figure 3-9 shows a typical multiprocessor configuration. This is a daisy chained configuration (TDO-TDI daisy-chained), that meets the minimum requirements of the IEEE specification. The emulation signals in this example are buffered to isolate the processors from the emulator and provide adequate control signal for the target system. One of JTAG test interface benefits is that you can slow down the test clock to eliminate timing problems. Multiprocessor systems should meet the following requirements: o The processor TMS, TDI, TDO and TCK signals are to be buffered to control timing skew better. o The input buffers for TMS, TDI, and TCK should have pull-ups to Vcc. This will hold these signals at a required value if the emulator is switched off. A pull-up resistor of 4.7k Ω is suggested for most applications. Figure 3-9.

14 Revision 1.00 JUL JTAG-connection settings The following emulator connection parameters can be configured in the tab Advanced of Target Configuration panel. On the tab you can set various parameters and conditions to ensure the correct emulator operation to debug the device. Below is a description of the available positions for adjustments in the integrated development environment Code Composer Studio v Parameters for connection several emulators to one PC Below you will find the parameters that are needed when connecting several Emulators to one PC. The key factor is to link each connection to a definite Emulator by its serial number. Select the Advanced tab in the Target Configuration editor. Select the connection. After that Connections Properties will appear on the right side. Set the parameter Use specified emulator only and after that enter the values into the Enter Serial Number and Enter Serial Number again fields. 14 Copyright 2013, Sauris GmbH

15 SAU510-USB ISO PLUS v.2 Revision 1.00 JUL Parameters for setting TCK frequency There are two ways to enable the clocking of the JTAG-chain. These are clocking at a fixed frequency and adaptive clocking. The fixed frequency can be used for most hardware where the maximum allowed TCK does not depend on the CPU frequency. The adaptive clocking is used for the devices that require dynamically changing TCK for operating in these devices the TCK is based on the clock frequency of the CPU. DaVinci is an example of such a device it includes ARM- and DSP-cores that have different clock frequency and the TCK in each moment depends on the frequency of the currently active core. To set the TCK in the CCS select tab Connections Properties and set TCK Frequency Divider range and TCK Frequency. You can initiate an additional frequency divider by setting Enable additional 8x TCK divider parameter Adaptive clocking mode On default TCK is generated by the emulator independently of the TCKR from the target. The TCK frequency is constant. But some processors require the TCK to be below some limit. The limit is set inside the processor and depends on the processor s own clock frequency, which can change considerably during the operating, e.g. because of PLL programming. Such processors have JTAG return clock frequency output gated by the required internal frequency. If this output is connected to emulator s TCKR input, the adaptive clocking mode allows the emulator to operate at the maximum frequency, that is possible for the processor. The reason is: in adaptive clocking mode the edge at the TCK is formed according to not only TCK, but also to the correspondence between TCKR-signal and the current TCK signal. The rising or falling edge will. Thus the rising or falling edge can never be generated before the previous rising/falling edge goes through Copyright 2013, Sauris GmbH 15

16 Revision 1.00 JUL 2013 TCK > TCKR circuit In this case maximum frequency is limited by divider. Adaptive clocking mode is usually used with ARM processors. Note: It is highly undesirable to set TCK frequency limit higher than 20 MHz in adaptive clocking mode. It can cause bugs in emulator-target system if tweaking connection for functioning on high frequency are changed during the adaptation. To set Adaptive clocking mode check the Enable adaptive clocking parameter in the connection properties Functioning without return clocking (TCKR). In some cases the system has to operate without return clocking signal (TCKR), for example when operating with ARM JTAG where TCKR signal is optional. Thereto there is a bypass way for the signal TCK -> TCKR beside all outside circuits. This way provides approximately the same delay as outside circuit does when it includes standard cable and 5 cm length of TCK->TCKR. There is an opportunity to increase this delay by the 4,8 ns (1/210 MHz) step. To enable operating without return clocking mode set Target doesn t provide TCKR signal in the TCKR signal mode parameter. After that set Additional delay for internal TCKR bypass path. 16 Copyright 2013, Sauris GmbH

17 SAU510-USB ISO PLUS v.2 Revision 1.00 JUL Control the impedance matching circuits There is an opportunity to connect the impedance matching circuits to TCKR and TDI pins to improve this signals quality. This connection is on by default. To connect the impedance matching circuits to TCKR and TDI you should set appropriate value in TDI and TCKR termination parameter Tweaking connection for functioning at high frequency There is an internal delay in generating TMS and TDO as compared with TCKR edge in Emulator because of galvanic isolation. TMS and TDO change in approximately 38 ns after the TCKR edge. Thus if you do not change the parameters indicated in this chapter the high TCK frequency is approximately 24 MHz. There is an opportunity to operate at higher frequencies. They are needed when using devices which generate their own TCKR signal which does not depend on the emulator TCK (e.g., some starter kits from Spectrum Digital that generate their own TCKR of 30 MHz frequency). The parameters for tweaking connection are as follows: ( Link delay ). This parameter sets the number of TMS and TDO delay cycles after they are generated in the emulator by JTAG-controller and before they come to the processor pins. Minimum value is 3 because of the count of synchronization flip-flops inside the emulator. Copyright 2013, Sauris GmbH 17

18 Revision 1.00 JUL 2013 If the delay of TMS/TDO generated from the rising edge of TCKR-signal exceeds one cycle of TCKR, the Link Delay should be increased by one, thus the value is to be 4. If the delay exceeds two cycles, the Link Delay is to be increased by 2, that makes the value of 5. ( Additional delay for TMS output, Additional delay for TDO output ). These parameters serve to set additional delay to TMS and TDO generating from 0 to 7 intervals 4.8 ns each. The delay should be adjusted if after choosing the clock frequency the existing TCKR >TDO/TMS delay brings to the situation when the TDO/TMS signals do not meet the requirements setup/hold of the target processor when they reach it. [POD_TMS_OFS] and [POD_TDO_OFS] enlarge the delays and move the TMS/TDO signal changing beyond the time limits where the change is prohibited. ( TMS/TDO output timing ) allows to enable the TMS/TDO generating on the falling edge of TCKR. It complies with the IEEE standard, but it allows a much lower value of max TCK frequency (approximately MHz) as the 38 ns delay (due to galvanic isolation) lasts not from previous rising edge to next rising edge of TCKR but from the falling edge to the rising edge of TCKR. Remember that there is a frequency limit in TMS/TDO sampling at the falling edge when adaptive clocking is active. You can also use this parameter to solve the problems with setup/hold requirements. Enabling the TMS/TDO sampling at the falling edge generates half period TCKR delay compared to the TCKR sampled at the rising edge. Note: if the divide coefficient is odd, the width of positive half-wave differs from the width of negative half-wave by 4,8 ns. Half-wave width can be unpredictable in the adaptive clocking mode JTAG output level clamping Emulator outputs voltage level can be changed from 1.65 to 5V regardless voltage level on PD pin. 18 Copyright 2013, Sauris GmbH
